The invention relates to a rail locomotive vehicle low-floor bogie, in particular to a low-floor bogie driving unit and a low-floor bogie. A driving motor (1) of the driving unit, a first gear box (3) used for driving a first wheel pair and a second gear box (5) used for driving a second wheel pair are installed on the outer side of a bogie frame (7), the driving motor is vertically installed, the first gear box and the second gear box are connected through a connecting rod device (4), a second transmission gear is installed at one end of the connecting rod device, and a second transmission gear is installed at the other end of the connecting rod device. The output shaft of the driving motor is connected with and drives the first transmission gear, the second transmission gear is meshed with the input gear in the first gear box, and the third transmission gear is meshed with the input gear in the second gear box. According to the invention, the transverse space required by the installation of the driving motor is reduced, the junction points of the output shaft of the motor are reduced, and the maintenance cost is effectively reduced.
本发明涉及轨道机车车辆低地板转向架,特别是一种低地板转向架驱动单元及低地板转向架。所述驱动单元的驱动电机(1)、用于驱动第一轮对的第一齿轮箱(3)和用于驱动第二轮对的第二齿轮箱(5)分别安装于转向架构架(7)的外侧,且驱动电机竖直安装,第一齿轮箱和第二齿轮箱经连杆装置(4)连接,连杆装置的一端安装第二传动齿轮,另一端安装第三传动齿轮,中部安装第一传动齿轮,驱动电机的输出轴连接并驱动第一传动齿轮,第二传动齿轮与第一齿轮箱内的输入齿轮啮合,第三传动齿轮与第二齿轮箱内的输入齿轮啮合。本发明减小了驱动电机安装所需横向空间,并减少了电机输出轴的联结点,有效降低了维护成本。
